When had reading ever produced fruit? If it could we'd just need to send books to starving countries and teach them to read. The fruit output would be amazing. We'd have to paraphrase the old saying: "Give a man fruit and you feed him today. Teach a man to read and he'll have fruit for a lifetime."
depends on the fruit really...I gotta say that some fruits will not exactly rush the digestive system along...but some (usually the most tasty) will send ya runnin' for the privvy
